Holley's printed instructions are mostly for fuel pumps, not regulators. I have found NOWHERE in the docs where the ports are specified, nor on the device itself. 30 minutes of google image search gave me a port identification image. It must be difficult for an old line speed company to identify parts of products. I will never buy Holley products again. Remember another company wants to sell but doesn't support their customers.
